6 Claims.

This invention relates to improvements in stapling machines and moreparticularly to improvements in the stapling machine of the classdescribed in the patent to Robert F. Stepbach, No. 2,303,509. 4

An object of the invention is to provide a supporting member for astapling machine which will enable staples to be inserted through thestaves, below the chime, into the had of the barrel at points inalignment with cleats which extend over the end of the barrel.

Another object of the invention is to provide a supporting segment for astapling machine for stapling barrel heads which does not meet withinterference from the cleats on the end of a barrel.

Another object of the invention is to provide a segment or support for astapling machine which stabilizes the machine in its operation.

Another object of the invention is to provide a segment or support for astapling machine having an improved chime engaging portion for backingup the chime when staples are being driven into the head.

Another object of the invention is to provide a structure which willhold a cleat in place on the end of the head While a staple is beingdriven through a hoop and an end of the cleat into the head.

Still other objects of the invention and the invention itself willbecome more apparent from the following description of an embodimentthereof which description is illustrated by the accompanying drawingsand forms a part of this specification.

In the drawings:

Fig, 1 is a side elevational view of a stapling machine disposed on theend of the barrel and showing the relative positions taken by thevarious parts prior to the time a staple is driven through the staves,below the chime, of the barrel into the head, the barrel and the machinebeing broken away and shown in section.

Fig. 2 is an enlarged fragmentary section through a barrel showing thechime and head together with a cleat and hoop secured in place by astaple.

Fig. 3 is a view taken on the line 3--3 of Fig. 2.

Fig. 4 is a view taken on the line 4-4 of Fig. 2.

Figs. 5, 6 and 7 are top plan, side elevational and bottom plan views,respectively, of the improved supporting segment cf my invention, and

Fig. 8 is a view taken on the line 8 8 of Fig. 4.

Referring now to the drawings throughout which like parts are designatedby like reference characters, the machine in its operation issubstantially as shown and described in the aforementioned Stepbachpatent. It comprises a supporting frame I which is arranged to overhangthe chime of the barrel being provided with a shoe or segment 2 which issecured in the frame by a bolt 3 in a manner similar to that describedin the patent. A supporting arm 4 extends across the barrel and rests onthe chime of the barrel at the opposite side. A handle 5 is provided foractuating the stapling mechanism which drives the staple 6 through thechime into the barrel when the handle is forced downward toward thehead.

Heretofore some diiiiculty has been encountered in maintaining a machineof this character in a vertical position. In actual practice the staplesare driven rather quickly and very often it happened that the operatordid not have the machineY disposed in a vertical relation to the head ofthe barrel with the result that the staple was driven into the head withone of the legs of the staple above and to one side of the other. Itwill be clearly seen from reference to Fig. 2 that when this occurs thatthe staples do not necessarily go into the center` of the head but mayeven miss the head entirely and extend above and below the head or be soclose to the surface of the head as to split the wood.

Furthermore, with the previous device it was difficult, if notimpossible, to position the stapling machine so that a staple could bedriven into the head at a point in alignment with the cleats whichextend across the head. It has been common practice to provide a steelcleat for extending across the head as best shown in Figs. 2` and 3which usually comprises a sheet metal member I0 having a raised rib I Iextending longitudinally of the cleat, the body of the cleat beingsecured to the head byv tacks I2. The end of the cleat adjacent thechime extends up inside of the chime at I4, across the top at I5, anddown the outside at I6 as best shown in Fig. 2. A hoop I8 extends aroundthe upper edge or chime of the barrel embracing the end IB of the strip.The hoop and cleat are secured in place by the staple 6 driven throughthe hoop, strip, the stave below the chime and into the head of thebarrel.

Previously it was necessary to drive these staples by hand because therib Il interfered with the placement of the stapling machine. This wasnot only a diicult operation but a timeexpending operation. By thepresent invention I provide a segment or support for the barrel whichcomprises an upwardly extending part 20 having a threaded opening 2| forreception of the screw 3 as previously described. Extending laterallyfrom the portion 20 on each side thereof is a pair of supportingsurfaces each of which comprises a flat bottom surface 23 having oneedge curved to provide an arc at 24 of one radius and the opposite sideat 25 curvedto form an arc of another radius. Intermediate theseportions there is provided a channel 21 as best shown in Figs. 6 and 7which separates the two surfaces 23 and extends upward toward the body20 a suincient distance to allow clearance space for the rib Il on thecleat. The channel may be ared outwardly at the ends as indicated at 28and 28'.

The edge walls 24 and 25 slant toward the upper side as best shown inFig. 8 so that the bottom surface is larger than the top surface 30.

It will thus be seen that the segment or supporting member is providedwith two surfaces of different curvature. This allows the supportingmember to fbe secured to the bottom of the stapling machine with eitherof the surfaces towards the chime of the barre1 to 'provide the surfacesof different radii for engaging chimes of barrels of different size.

It will also be seen that the channel 21 allows the machine to besupported directly over the cleat and to permit driving of the staplethrough the hoop and end of the cleat to the barrel. During thisoperation the cleat is engaged by the bottom of the segment adjacent thechannel 21 and the pressure of the stapling operation and the weight ofthe stapling machine holds the cleat firmly against the head of thebarrel while the edges 24 engage the cleat at the portion I4 and pressit against the inside of the chime of the barrel thus holding the cleatin a firm engagement with the chime and head while the staple is beingdriven in place. The slanting character of the walls 24 assures that thepressure will be exerted adjacent the head and at the base of the chime.All of these features cooperate to assist in the more firm attachment ofthe cleat and hoop to the head and chime of the barrel.

I also contemplate forming the channel 21 wider to enable the segment tobridge wooden cleats, which may be somewhat larger than steel cleats,when it should be desired. It should also be observed that the extensionof the segment laterally is such that the stapling machine may bepositioned on the barrel and it will automatically take an uprightvertical position wherein both prongs of the staples are in properalignment to be driven on a horizontal plane. In this manner properengagement of the staple with the barrel head in the midsection isassured thus eliminating the necessity of pulling out staples andredriving which was previously a common occurrence where this Verticalstability was not provided.

Having thus described my invention I am aware that numerous extensionsand departures may be made therefrom but without departing from thespirit or scope of the invention.

I claim:

1. In a stapling machine, a supporting member for said machine,comprising a shoe having a. lower face for engagement with the barrelhead and forward and rearward portions shaped for engagement with barrelchimes of different diameters, said shoe extending laterally on eachside from the center to hold said stapling machine 1n proper alignmentwith the barrel.

2.
